CYSTS AND “PSEUDOCYSTS” OF THE MENISCI OF THE KNEE JOINT

Abstract
Consecutive [human] knee arthrotomies (636) were subjected to a prospective study, including the incidence, clinical presentation and operative findings of meniscal cysts and associated pathological conditions. The clinical differential diagnosis was studied in detail, and from this, the importance of a specific clinical sign indicating a torn lateral meniscus was realized. This sign was termed a pseudocyst. Meniscectomy was the operation of choice and not simple cyst removal. The high incidence of associated meniscal tears and other less frequent joint pathological conditions justified a standardized approach designed to assess the meniscus and other intraarticular structures, rather than a simple incision over the joint-line swelling.
